      <text>{{ selectedMovie }}</text>
    </picker>

<script>
export default {
  data() {
    return {
      movieList: ['电影A', '电影B', '电影C'],
      selectedMovie: '电影A',
    };
  },
  methods: {
    changeMovie(e) {
      this.selectedMovie = this.movieList[e.detail.value];
    },
    reserveTicket() {
      // 发送请求到后端，进行预订操作
      // ...
    },
  },
};
</script>

// 利用uni.request发送请求，并在处理函数中进行影票预订操作
uni.request({
  url: 'https://api.example.com/reserveTicket',
  method: 'POST',
  data: {
    movie: selectedMovie,
    userId: userId,
  },
  success(res) {
    console.log('影票预订成功');
  },
  fail(res) {
    console.log('影票预订失败');

<template>

      <text>{{ movie.name }}</text>

    </view>
  </view>
</template>

<script>
export default {
  data() {
    return {

      },
      fail(res) {
        console.log('获取推荐电影失败');
      },
    });
  },
};
</script>

// 处理请求，根据用户喜好查询电影数据并返回
app.get('/getRecommendedMovies', (req, res) => {
  const userId = req.query.userId;
  // 根据userId查询用户喜好
  const userPreferences = getUserPreferences(userId);
  // 使用用户喜好查询电影数据
  const recommendedMovies = getMoviesByGenre(userPreferences.genre);
  res.send(recommendedMovies);
});
